Try Remington Golden bullets, Federals or American Eagle. Those are some good and easy to pay for .22 ammo. My 10/22 shoots them all pretty good, if ammo is a problem.
Only really know of a good one, that is the K22 Masterpeice. Maybe Colt Frontier Scout Buntline or Ruger single-six with 9 1/2 bbl.
The Ruger single ten convertible (.22 LR and .22 WMR cylinders) looks to be about $450 vs almost $700 for the SW 617 (which I think is the current production model).
Is there a drawback to the convertible Ruger? Seems the MSRP is higher than the non-convertible (.22 LR cylinder only) version.
I have given up buying the real cheap ammo - bulk copper coated hollow point Federal, Winchester, Remington - the accuracy stinks even at 25 yards. The also cheap Federal Lightning and CCI Blazer are OK (lead solid point). But, I like the CCI Mini Mags and Standard Velocity much better.
That's what I've got in stainless. It's a great shooter, can bounce cans all over the yard with it. Also very accurate when target shooting. Honestly, I've not put the mag cylinder in it.
I picked up a Heritage Rough Rider with 6 1/2" barrel and fiber optic sights at Bradis, 2 days ago. After about a hundred fifty rounds so far its as accurate or better that any other .22 revolver I've shot at half the price. I'm getting great groups from Aguila hyper velocity ammo.
This came with the .22 mag cylinder also but have yet to put it in.
i also vote ruger. had a single six ,it was great.also had a mark I standard and it was accurate and never ever misfired or jammed and i shot an incredable amount of lead through it. six inch or more barrel is best on whatever you get.
